Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection technology, specifically to a vehicle survival space detection and measurement device. Background Technology

[0002] The assessment of survival space in passenger vehicles is a crucial step in vehicle safety performance evaluation, especially in destructive tests such as rollovers, where the measurement of survival space directly impacts the safety of passengers and drivers. According to international standard R66, "Unified Provisions for Certification of the Strength of the Superstructure of Large Passenger Vehicles," and national standard GB17578, "Strength Requirements and Test Methods for the Superstructure of Passenger Vehicles," passenger vehicles must ensure that the survival space meets minimum dimensional requirements after a rollover test to prevent occupants from being crushed due to vehicle deformation. Survival space in a passenger vehicle refers to the remaining space available for survival by the occupants at the front, middle, and rear main beams during and after the rollover test.

[0003] Vehicle survival space testing is a destructive test. Currently, the measurement of bus survival space mainly relies on manual operation, using a simple measuring device composed of bamboo skewers, foam boards, or deformable templates. The template is fixed on the same side as the bus seat, and the foam board is placed between the bus seat and the bus body, with one end of the bamboo skewer resting against the bus body and the other end embedded in the foam board. According to testing regulations, measuring devices are installed at three measurement points: the front door, the rear door, and the middle of the bus, and tests are conducted at each point. After the bus undergoes a rollover test, personnel enter the overturned bus to collect data on the state of the foam board and bamboo skewers, comparing the data with the initial state to obtain the bus survival space test data. However, this method has significant drawbacks: First, the measurement accuracy of tools such as bamboo skewers is low, and the skewers may fall off or deform during the test due to vehicle rollover, causing data loss or errors. Second, the interior environment of the vehicle after the test is complex, potentially containing oil stains, water stains, high-voltage battery leakage, or even explosions. Test personnel must enter the rollover vehicle to conduct measurements, which is not only difficult but also poses safety hazards such as cuts from glass shards and difficulty escaping in case of sudden danger. Furthermore, the sharp edges and burrs of the bamboo skewers can easily cause additional injuries to test personnel. These problems seriously affect the accuracy, efficiency, and safety of the test, necessitating a remotely operated, high-precision, and safe automated testing device to replace the traditional method. Summary of the Invention

[0004] The present invention aims to provide a vehicle survival space detection and measurement device to solve the problems of safety hazards and low testing efficiency in the existing technology.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a vehicle survival space detection and measurement device, comprising:

[0006] The detection device includes an intelligent acquisition terminal, which includes a data acquisition module, a controller, and a wireless communication module. The data acquisition module includes a survival space detection module. The survival space detection module and the wireless communication module are electrically connected to the controller. The survival space detection module is used to detect the survival space of the vehicle. The controller is used to generate acquisition information based on the data acquired by the survival space detection module and send it to the backend server through the wireless communication module.

[0007] The backend server is connected to the network of the detection device. It is used to process and analyze the collected information to obtain detection results, display the results, and send them to the monitoring terminal.

[0008] The monitoring terminal is connected to the backend server via network and is used to retrieve and display the detection results from the backend server.

[0009] Preferably, the survival space detection module includes a first distance detection sensor and a second distance detection sensor. There are multiple first distance detection sensors and multiple second distance detection sensors. The distance detection sensors are arranged sequentially between the roof and the floor of the vehicle. The first distance detection sensors are located at the bottom, and the distance between each first distance detection sensor and the vehicle body is the same. The second distance detection sensors are located at the top, and the distance between the second distance detection sensors and the vehicle body gradually increases from bottom to top.

[0010] More preferably, the detection device further includes a mounting frame on which each distance detection sensor is mounted.

[0011] More preferably, the height difference between adjacent distance detection sensors is 8–15 cm.

[0012] More preferably, the distance between the lowermost second distance detection sensor and the vehicle body is 150mm, and the distance between the uppermost second distance detection sensor and the vehicle body is 250mm.

[0013] Preferably, the backend server includes a data storage module for storing collected data and information for displaying detection results.

[0014] Preferably, the detection result display information includes abnormal values ​​of the bus survival space. The back-end server includes a data collection and analysis module, which is used to compare the detection values ​​after the rollover test in the collected information with preset limits to generate abnormal values ​​of the bus survival space. The abnormal values ​​of the bus survival space are displayed in different color grades.

[0015] More preferably, the detection result display information also includes living space change information, and the server further includes a data processing module for performing time-series processing on the continuously collected living space detection values ​​during the detection process, and generating living space change information after eliminating noise through a filtering algorithm.

[0016] In another preferred embodiment, the backend server further includes a parameter adjustment module for allowing administrators to adjust the detection parameters.

[0017] Preferably, the number of intelligent data acquisition terminals is three, which are respectively installed at the front, middle and rear body beams of the vehicle.

[0018] This utility model has the following advantages:

[0019] 1. All distance detection sensors are set up according to regulations. The detection device is responsible for accurate front-end data acquisition, the wireless communication module enables real-time data upload, the back-end server performs professional analysis, and the monitoring terminal displays the results intuitively. Seamless integration of each link reduces intermediate data loss during data flow, achieving real-time data transmission. Live space data collected at the front end can be quickly uploaded to the back-end, avoiding data delays and significantly improving overall detection efficiency. Furthermore, no manual entry into the destructive testing site is required for data collection, effectively protecting the safety of personnel.

[0020] 2. The intelligent data acquisition terminal automatically completes data acquisition, processing, and wireless transmission through the controller, eliminating the need for manual recording or uploading and reducing human intervention. This not only saves labor costs but also avoids problems such as omissions and errors that may occur during manual operation, thus improving data reliability.

[0021] 3. The monitoring terminal displays the test results intuitively, allowing managers, rescue personnel, quality inspectors, and others to quickly understand the status of the vehicle's survival space without having to interpret complex raw data.

[0022] 4. The survival space of the rollover test vehicle is measured by the detection device, and the back-end server processes the detection data. By comparing the survival space data before and after the rollover, the test results can be obtained, which solves the problems of safety hazards and low testing efficiency of existing detection technologies. Moreover, it can also monitor the impact of vehicle deformation on the occupant survival space in real time, which is convenient for subsequent vehicle design improvements and optimizations.

The monitoring terminal can be a portable device used by staff, such as a mobile app; in this embodiment, a portable device, preferably a laptop computer, is used.

[0033] Preferably, the living space detection module includes a first distance detection sensor 3 and a second distance detection sensor 4. The distance detection sensor can be a laser rangefinder or an ultrasonic sensor. In this embodiment, a laser rangefinder of model SICK DT50-P2145 is preferred. There are multiple first distance detection sensors and multiple second distance detection sensors. The height difference between adjacent distance detection sensors is 8 to 15 cm. In this embodiment, 10 cm is used. The distance detection sensors are arranged sequentially in a vertical direction between the roof and the floor 12, specifically positioned within a space of 0–1250 mm from the floor 12 from bottom to top. The first distance detection sensor is located at the bottom, specifically positioned within a space of 0–500 mm from the floor 12, and all first distance detection sensors are 150 mm away from the body 11.
